, NATHANIEL G. HOLLAND, or nonronx, vmemra, ASSIGNOR To one DOMINION MARINE RAILXV-AY oonroearron, or nonronx, VIRGINIA, A CORPORATION or VIRGINIA HEATING FURNACE 'lhe invention relates to a furnace construction, especially designed for heating dwellings or other edifices or enclosures.

' An aim of the present invention'is to pro vide a, furnace construction, wherein the parts thereof are so formed as to permit easy assemblage and, portability fol-ready transit prior to installation, while the furnace, when installed will operate, with minimum fuel 0 consumption and resultant maximum heating qualities in water. or steam heating systems,"the parts being readily erected and knocked down with dispatch.

Another aim of thinvention is to provide a furnace construction, wherein the coils for the circulation of the fluid are arranged in a novel manner for quick heating of the fluid. A further aim of the invention is the provision 'of'a furnace construction'of the char-1 embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawings Figure 1 is an elevation of a furnace constructecl in accordance with the invention,

portion thereof being broken away to illustrate the internal organization.

Figure 2 is a side view, the casing being broken away.

Figure 3 is a sectional view on the line 33 of Figure 1.

Sim1lar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, the

" furnace comprises a lower burner body 5 molded or casted to present solid opposite ends 6, these being in the nature of vertical walls and a back '7, the upper portion of the body .5 being formed with a horizontal ledge 8 which, at the front thereof and also the end 6, has bolted or otherwise secured thereto the front section 9 equipped with a swinging door 10'so that access may be had to the fire chamber 11 within-this body 5. Extended through the back 7 into the chamber 11 is a burner 12 of any approvedtype and which receives its fuel from any'suitab'le source of supply.

Superposed relative to the body 5 is an upper housing including the'end plates 13,

front and back plates 14 and 15fand thetop plate 16, the end plates at their rear and forward edges being outturned to provide abutment flanges 17 for the front and rear plates 14 and 15, these being made fast to said flanges 17 by'fas'teners 18. Likewise, the top plate 16 is'provide'd with marginal flanges lS'fOr-the-ends, front and rear plates which are made fast thereto by fasteners 20. These plates at their inner faces are covered by asbestos '21 and atitheir lower ends are anch'ored upon the body'5 in any suitable manner within a rim'22 on the latter at the upper portion thereof.

Within the combustion chamber 23 formed bythehousing is fa fluid circulating unit of the furnace whicliincludes spaced lower cylindrical drums 24, these having centrall of their ends anchoring studs 25 which pass through suitable companion openings in the front and rear-plates 14 and 15 and are fitted with nuts 26 which make ifast'the said drums thereto, it being intended that the drums rest upon the ledge 8 on the body 5. These drums 24, between their ends, j are joined together through the 'inedium of cros's ipes 27, the latter and the drums being ormed with coupling nipples I 28 for detachable connection therewith lof upwardly directed ipes 29 and these through the medium 0 coupling 'nipples'31 communicating with a superposedlcom'paratively large head drum 32 arranged in theupper'portion of the housing,

the ends of this drum 32 .beingprovided with studs 33 which pass through suit-ableiopen- V ings in the front ,andir'ear plates 14 and 15 and carry nuts 34 for the 'anchoring ofsaid studs therein. 7 v Detachably coupled with nipples 35 rising from the drums 24 is a series of coils 36, these being coupled through the medium of nipples 37 with the drum 32, the coils being disposed in upwardly convergent relation to each other at opposite sides of the longitudinal center of the housing, and likewise the upstanding port-ions of the pipes .29 converge upwardly within said housing.

Bridging the drum 32 are saddle straps 38 constituting hangers for horizontally disposed perforated bafiies 39, these being located on opposite sides of the drum 32 above the coils 36 of the fluid circulating unit, while leading from the drum 32 through the top plate 16 of the housing is a fluid distributing.

main 40 and adapted to be connected to the top plate 16 for communication with the chamber 23 is a spent products of combustion outlet ll'for aflstackfor the furnace.

The drums 24, at their outer sides, have opening thereinto pipe inlets 42, these being extended without the. furnace and a fiuid supply may be connected to either of the same, it being understood, of course, that the one not connected to the fluid supplyis plugged in any suitable .manner. Therefore, it may be seen that the fluid supply can be admitted through either end of the furnace at the option of the user thereof.

The front plate 14 of the furnace is provided with a swinging door 43 so that access may be had to the chamber 23 for the cleaning of the latter or for repair purposes or to permit the assembling of the circulating unit or the knocking down thereof. a

It is deemed needless to describe in detail the working of the furnace, in its entirety, because this should be obvious, and therefore a more extended explanation has been omitted.

What is claimed is I v Y 1. A furnace construction, comprising a lower body assembly forming a fire chamber and having an upper ledge, a superposed housing having separable ends, front, back and top detachably connected with each other, the ends, front and back superimposed upon the lower body assembly,-a fluid circulating unit within the housing including lower spaced connected drums, an upper drum, tubes detachably connected with said drums for communication with each other, a plurality of coils detachably connected with the lower and upper drums and upwardly converging, baflies arranged on opposite sides of the upper drum and saddle, straps bridging said upper drum andforming hangers for the baffles, studs on the endsof the drums and engaged in the front and back of the housing, and means engaging the studs exteriorly of the housing.

2. A furnace construction, comprising a lowerbody assembly forming a fire chamber and having an upper ledge, a superposed housing having separable ends,fr ont, back and top. detachably connected with each ing, and means engaging the studs without the housing, the said lower drums being superimposed upon the said ledges.

3. A furnace construction, comprising a lower body assembly forming a fire chamber and having an upper ledge, a superposed housing having separable ends, front, back and. top detachably connected with each other, the ends, front and back superimposed upon the lower body assembly, a fiuidcirculating unit within the housing including low er. spaced connected drums, an upper drum,

tubes detachably connected with said drums for communication witheach other, a plurality of coils detachably connected with the lower and upper drums and upwardly converging, bafflcs arranged on opposite sides of the upper drum, saddle straps bridging said upper drum and forming hangers for the baffles, studs on the ends of the drums and engaged in the front and backofthe housing, means engaging the studs, the said lowerdrums being superimposed upon the said ledges, and means for admitting fluid to either of the lower drums. In testimony whereof I afliX my signature.

NATHANIEL G. HOLLAND.
